Energy-intensive building

Developed by Flamingo Dai Lai Joint Stock Company, Forest in the Sky is a unique real estate project with advanced green technologies located in Hanoi.

Vietnam’s Coteccons served as the construction contractor for the eco-friendly complex. Forest in the Sky pioneers a new sustainability standard for Vietnam, emphasizing a visual appeal that is grounded in durability, comfort and energy and water-conserving features.

With its distinctive architecture, the four sides of Forest In The Sky are covered with over 50,000 trees, including shrubs, vines and colorful flowers. From a distance, the building resembles a tropical jungle full of vitality and brilliance. From within the building, residents can enjoy a panoramic view of Dai Lai Lagoon and Tam Dao Range.

Residents benefit from lower utility bills as all homes feature energy-efficient lighting, external window shading and high-efficiency hot water boilers, ensuring the building is as “green” on the inside as it is on the outside.

Forest in the Sky has received final EDGE certification from SGS Vietnam.

Owner approach of sustainability

The green “jungle” building is a prime example of green living and will set a new sustainability standard for Vietnam building practices. Besides its green exterior, which helps insulate the building, the tower is equipped with numerous sustainable features. Under the lush greenery, the interior and exterior walls are made of eco-friendly cellular lightweight concrete blocks that offer optimal insulation from extreme heat and cold as well as sound.The building also uses high-efficiency hot water boilers, low-flow plumbing fixtures, and energy-efficient lighting to reduce energy usage. Future residents will not only be able to enjoy the amazing greenery and stunning views of the location, but will also enjoy the benefits of green living such as low utility bills.

Architectural description

With its distinctive architecture, the four sides of Forest In The Sky are covered with over 50,000 trees, including shrubs, vines and colorful flowers. From a distance, the building resembles a tropical jungle full of vitality and brilliance. From within the building, residents can enjoy a panoramic view of Dai Lai Lagoon and Tam Dao Range.
As part of the 123-hectare Flamingo Dai Lai Resort which is dedicated to the landscape, residents of Forest In The Sky can see trees and flowers blooming inside out, not in a suffocating but delicate way based on the subtle blending and smooth transition between this lush vegetation with other architectural and interior factors including ceiling-to-floor windows, wooden items, and lighting systems. All is combined in harmony to relieve the monotony of living in concrete and magnify enjoyment of every resident utmost.

Life Cycle Analysis

    Arch. Maria Chiara Pastore of Stefano Boeri Architetti, famous for creating the vertical forests model for sustainable residential buildings embodied by Milan’s Bosco Verticale (Vertical Forest), emphasized how its vegetal system contributes to the construction of a microclimate, produces humidity, absorbs CO2 and dust particles and produces oxygen.

    This is not only instrumental in curbing climate change but also utilises accessible building materials for large-scale construction projects. Compared to concrete, steel, cement and glass, wood requires less energy to produce and stores – rather than emits - carbon.

    Dr Michael Ramage, Director of the Centre for Natural Material Innovation at the University of Cambridge, instrumental in the design of the “The Toothpick” (a wooden skyscraper set to become the second tallest building in London), discussed “super-tall timber”. He explained how wood construction involves cross-laminated timber, a material made of many sheets of wood glued and compressed together, is stronger than steel and a viable candidate for building skyscrapers

Indoor Air quality

    Integrating urban forests into architecture leads to breathtaking results. Sometimes referred to as treescrapers, these buildings have plenty to offer beyond their unique architecture. Implementing sustainable principles, they are a breath of fresh air in high density cities — literally. Urban forests provide us with better air quality by increasing the available oxygen. Also, they ensure a safe habitat for animals that in most cases wouldn’t survive the harsh conditions of crowded cities.
